"Earth Choice" Laundry Cup drainer

thingiverse

Here's a solution to turn Earth Choice laundry liquid cups into efficient dispensers. Rather than having the cups stick together after use, which makes them difficult to place in the washing machine, simply position one cup underneath and the used cup on top when it's time for a new wash. Any excess liquid will drain from the used cup into the empty one. After about 10-12 washes, the bottom cup should be full and ready to go for the next load. This clever design features two separate parts that easily snap together.
